。[Problem to be solved by the invention] However, by making the roughness of the upper and lower work rolls different,
When attempting to roll a steel plate with different roughness on the front and back sides, the following problems occurred. That is, as shown in FIG. 4, the steel strip 22 is attached to the payoff reel 21, and the take-up reel 23 is
While winding the steel strip 22, a pair of work rolls consisting of an upper work roll 24 or a briny 1-roll and a lower work roll 25 are dull rolls are used. If you try to roll steel plates with different roughness, the back side of the steel strip 22 will be braked by the dull roll during rolling, so the steel strip 22 or the fifth
There is a problem in that the steel strip 22 warps downward in the longitudinal direction as shown by the solid line in the figure. Moreover, if the brazing roll 1~ roll and dull roll are reversed vertically, there is a problem in that the steel strip 22 becomes warped upward as shown by the dotted line in FIG. This warping includes warping in the longitudinal direction of the steel strip 22 (referred to as L warping) as shown in FIG. 5, and warping in the width direction of the steel strip 22 (W ) and a vertical warp (referred to as C warp), which significantly impairs the quality of the final product, so this warp, especially C warp, should be kept within ±1.
Although it is necessary to suppress the warpage to within 0mm (+ means upward warpage, and means downward warpage), such technology has not been established in the past.

A method for manufacturing a steel plate with different roughness on the front and back sides by rolling it using a roll venter type shape adjustment device consisting of three rolls that flattens the top or bottom warpage of the steel plate caused by the surface roughness of the steel plate. This is an embodiment of the method for manufacturing a steel plate having different roughness on the front and back surfaces, in which the rolling position of the shape adjusting device is +5 to +15 mm.

装置とを用いて圧延する製造方法である。[Function] The method of manufacturing a steel plate having different roughness on the front and back surfaces according to the present invention includes one or more pairs of work rolls for rolling steel plates, which are designed to have different surface roughness on the upper and lower sides, and the surface roughness of the upper and lower rolls. This is a manufacturing method in which rolling is performed using a roll-henter type shape adjusting device consisting of three rolls that flattens the top or bottom of the steel sheet caused by different thicknesses.

ー式形状調整装置により矯正し、鋼板の幅方向に反る反
りを±１０ｍｍ以内になるようにしたのである。This was done for the following reasons. Since a steel plate with different roughness on the front and back surfaces is rolled, it is natural that the work rolls, which determine the surface roughness of the steel plate, must be finished with different surface roughnesses. However, when a steel plate is rolled with a pair of rolls with different surface roughnesses, the steel plate is likely to be braked by the relatively coarse surface of the rolls, causing the roll surface to warp in the direction of the target. . There are two types of warping: warping in the longitudinal direction of the steel plate and warping in the width direction of the steel plate.In particular, warping in the width direction of the steel plate is difficult when considering the quality of the final product.
It must be within 10mm. Therefore, a steel plate that is warped upward or downward by rolling with work rolls with different roughness on the upper and lower sides is corrected using a roll-hender type shape adjustment device consisting of three rolls, and the warpage in the width direction of the steel plate is corrected by ±10 mm. I tried to keep it within the range.

矯正されていす、圧下位置が＋１５龍を超えると、矯正
過剰となり上反りになる。このような理由から形状調整
装置の圧下位置を」−５〜＋１５ｍｍとしたのである。Further, as an embodiment of the method for manufacturing a steel plate having different roughness on the front and back surfaces, the method for manufacturing a steel plate having different roughness on the front and back surfaces is as follows:
The downward position of the shape adjusting device is +5 to +15 mm. The reason is as follows. In other words, as mentioned above, the warpage in the width direction of the steel plate must be within ±10 degrees, but what is the relationship between this width direction warp and the rolling position of the shape adjustment device, and in the case of downward warpage? I investigated. The results are shown in FIG. Warpage is ±10m
If the reduction position is less than +5 mm, the downward curvature will be completely corrected, and if the reduction position exceeds +15 mm, it will be overcorrected and the chair will be warped upward. Become. For this reason, the downward position of the shape adjusting device was set at -5 to +15 mm.

配置されている。[Example] In order to confirm the effects of the present invention, a three-roll bender type shape adjusting device was installed on the roll exit side of a skin pass mill configured as shown in Fig. 1, and the roughness was adjusted on the front and back surfaces. Rolled different steel plates. Steel strip 2 unwound from payoff reel 1
was rolled by a pair of work rolls consisting of a pair of upper and lower dull rolls 3 and 4, and then rolled by a pair of work rolls, the upper being a bride roll 5 and the lower being a dull roll 6. After this 30-
The warp was corrected using a rubender type shape adjusting device 7, and the film was wound up using a take-up reel 8. In this case, since the steel strip 2 warps downward, the three rolls of the shape adjustment device W7 are arranged so that both ends are on top, the middle is on top, and a flat plate is wound on top.

るとともに、加工後の製品の粗さ調整が不要となる。When rolling as described above, the rolling position of the shape adjusting device N7 was maintained between +5 and +15 degrees. Then, a sample was taken from the rolled steel strip 2 to measure the amount of warpage in the width direction, and when the warp was measured, the warp in the width direction was within ±10 mm over the entire length of the steel strip 2. It was confirmed that the method can produce a steel plate with different roughness on the front and back surfaces without causing large warpage.6 [Effect of the invention] The present invention can produce a steel plate with different roughness on the front and back surfaces without causing any harmful warpage. Different steel plates can be manufactured, expanding the range of uses, and eliminating the need to adjust the roughness of the product after processing.
